Relai App Review 2026 and Why Switzerland's Zero-Fee Bitcoin DCA Actually Delivers

A Swiss Bitcoin app lets you buy up to 100 EUR or CHF worth of bitcoin every month without paying any trading fees. The catch? There isn't really one, as long as you understand what "zero-fee" actually means and who this product is designed for.

Relai has positioned itself as Europe's simplest Bitcoin savings app, and after examining the fee structure, user feedback, and regulatory positioning, the core claim holds up. But "simplest" comes with tradeoffs that matter depending on how you plan to use it.

What Relai Actually Offers

Relai is a Bitcoin-only, non-custodial savings app based in Switzerland. When you buy bitcoin through the app, the coins go directly to a wallet you control rather than sitting on an exchange. This "not your keys, not your coins" approach distinguishes Relai from custodial platforms like Coinbase or Kraken where the exchange holds your bitcoin until you withdraw it.

The app supports purchases via bank transfer (SEPA), cards, Apple Pay, and Google Pay. Minimum purchase amounts start at 25 CHF, and the interface is deliberately stripped down: buy, sell, view your wallet. That's essentially it.

For recurring purchases, you can set up automatic weekly or monthly buys that execute without you logging in. This is the dollar-cost averaging (DCA) functionality that forms the heart of Relai's value proposition.

The Zero-Fee Structure, Explained Precisely

Relai's CEO Julian Liniger announced in December 2024 that the company had "permanently lowered our fees from 2.5% to 0.9%" while maintaining the zero-fee monthly allowance. Here's how the fee structure breaks down in 2026:

Standard trading fee: 1% per buy or sell up to 100,000 EUR/CHF, reducible to 0.9% with a referral code (10% discount).

Zero-fee allowance: Your first 100 EUR/CHF of auto-invest purchases each month incurs no Relai trading fee. This is limited to one transaction per month under the DCA/savings plan feature.

Payment method surcharges: Bank transfers and SEPA have no additional payment fee beyond the trading fee. Card purchases (including Apple Pay and Google Pay) add 1.5-3% on top of the Relai fee.

Network fees: Relai covers the on-chain Bitcoin network fee for purchases rather than passing it to customers.

So if you set up a monthly 100 EUR auto-invest via bank transfer, you pay exactly zero in Relai fees for that transaction. That's 1,200 EUR/CHF per year you can invest without paying trading commissions, a meaningful advantage for someone building a Bitcoin position gradually.

The limitation is important: only the first 100 EUR/CHF monthly auto-invest qualifies. Additional purchases that month incur the standard 0.9-1% fee. And card payments always add the 1.5-3% surcharge regardless of the monthly allowance.

How This Compares to Traditional Exchanges

Major exchanges like Coinbase and Kraken have normalized sub-1% taker fees with tight spreads. On pure percentage terms, Relai's 0.9-1% is competitive but not exceptional for standard purchases.

Where Relai differentiates itself:

Non-custodial by default. Your bitcoin goes straight to your wallet. You're not exposed to the exchange-custody risk that materialized catastrophically with FTX. For users who would otherwise buy on an exchange and then withdraw to self-custody, Relai eliminates that extra step (and the withdrawal fees that come with it).

Zero-fee monthly DCA. No major exchange offers a comparable fee-free recurring buy feature at this level. For small, consistent savers, this is genuine value.

Simplicity over features. There are no altcoins, no leverage, no order books, no limit orders. The app is designed for people who want to save in bitcoin, not trade it.

The tradeoffs:

Card fees eat into convenience. If you want instant purchases via card rather than waiting for SEPA settlement, you're paying 1.5-3% on top of the trading fee. That can push total costs to 2.5-4%, which is expensive.

Spreads exist but aren't broken out. Independent reviewers note that Relai's pricing incorporates spreads on the BTC/EUR or BTC/CHF rate. These are described as "small but present," though less than some larger platforms. Serious traders who want transparent order-book pricing won't get it here.

Settlement times. Bank transfers can take up to three days to settle, and some users report payout fees around 1% when selling. For anyone who needs fast liquidity or frequent trading, this isn't the right tool.

Regulatory Standing in 2026

Relai operates under Swiss regulation as a member of VQF (Verein zur Qualitätssicherung von Finanzdienstleistungen), a self-regulatory organization recognized under Swiss anti-money-laundering law with FINMA oversight.

The company also obtained a Markets in Crypto-Assets (MiCA) license from France's AMF, enabling regulated operations across much of the EU. This came with a significant change: full KYC onboarding became mandatory from October 31, 2024.

Earlier versions of Relai marketed a quasi-anonymous, data-minimal experience. That's gone. New users now complete standard identity verification, which brings Relai in line with MiCA requirements and mainstream regulated brokers.

For users who valued the earlier privacy-forward approach, this is a loss. For users who want regulatory legitimacy and the protections that come with it, the MiCA license represents maturation rather than retreat.

Who Should Use Relai

Relai makes sense for a specific type of user:

European residents in Switzerland or the 20+ EU countries Relai serves (including Germany, France, Netherlands, Spain) who want to set up recurring Bitcoin purchases without managing exchange accounts and withdrawals.

Beginners who find exchange interfaces intimidating. If order books, limit orders, and withdrawal procedures feel overwhelming, Relai's stripped-down interface removes that friction entirely.

Long-term savers, not traders. If your strategy is "buy 50-100 EUR of bitcoin monthly and hold it," the zero-fee DCA allowance delivers real value. If you're trying to time entries, use leverage, or trade actively, this isn't your tool.

Self-custody advocates. The non-custodial model means you control your keys from purchase. For Bitcoiners who prioritize sovereignty, this eliminates the intermediate step of holding coins on an exchange.

High-net-worth individuals can access Relai Private for purchases in the 100k-250k CHF/EUR range with reduced percentage fees while still receiving coins into self-custody.

Who Should Look Elsewhere

High-volume or frequent traders will find the lack of advanced features limiting and may get better pricing on major exchanges with direct order-book access.

Card-payment users face 1.5-3% surcharges that make Relai expensive compared to alternatives.

Users who need fast liquidity should note that settlement times and payout fees create friction for anything other than buy-and-hold strategies.

The Bottom Line

Relai's zero-fee monthly DCA actually works as advertised if you use it as designed: set up a recurring bank-transfer purchase of up to 100 EUR/CHF, and you pay no Relai trading fee on that transaction. The app covers network fees. Your bitcoin goes directly to your wallet.

For a European resident who wants to stack sats consistently without learning exchange mechanics or managing custodial risk, this is a compelling proposition. The app store ratings (around 4.5-4.6 stars across major platforms with over 100,000 reviews) reflect genuine user satisfaction with the onboarding simplicity, clean design, and hardware-wallet integration.

The fee structure isn't the cheapest for every use case, and the product lacks features that active traders need. But Relai isn't trying to compete with full-featured exchanges. It's a Bitcoin savings app, and within that narrow scope, the execution is solid.

If your goal is to build a Bitcoin position gradually over years, spending a few minutes each month checking an app while your purchases happen automatically, Relai delivers exactly that. The zero-fee allowance and non-custodial architecture aren't gimmicks. They're genuine differentiators for the specific audience this product serves.
